What the PA DEP test records show for Springfield Township
ZIP codes don't follow township lines, so the 2 ZIP codes below also take in some homes just outside Springfield Township.
| ZIP | Tests | Median pCi/L | 4+ pCi/L | 10+ | 20+ |
|---|---|---|---|---|---|
| 17360 | 1,543 | 7.5 | 63.4% | 41.6% | 24.7% |
| 17327 | 1,797 | 5.9 | 60.8% | 35.6% | 20.6% |
| York County | 98,845 | 4.3 | 52.5% | 26.8% | 13.1% |
- ZIP 17360 (about 51% of Springfield Township's land): median 7.5 pCi/L across 1,543 tests, 24.7% at 20 or higher, top reading 318. Basement median 8, first floor 4.6.
- ZIP 17327 (about 29% of Springfield Township's land): median 5.9 pCi/L across 1,797 tests, 20.6% at 20 or higher, top reading 397. Basement median 6.4, first floor 3.2.
The spread inside Springfield Township runs from 60.8% of tests high in 17327 to 63.4% in 17360.
Half of the story is the median. The other half is the tail: 38.4% of tests here were 10 pCi/L or higher and 22.5% were 20 or higher. The top reading on record in these ZIP codes is 397 pCi/L. Neighboring houses can differ by a factor of ten, so none of this tells you what your house is. It tells you the odds are high enough that a $15 to $30 test kit is worth buying.
Tests people chose to run, not a random survey. Details on the York County radon levels page.
Basement readings versus first-floor readings
In ZIP 17360, basement tests have a median of 8 pCi/L, while tests taken on the first floor have a median of 4.6 pCi/L (92 first-floor tests). The gap is smaller than in most of the county, which means readings upstairs here are not much of a relief from the basement number.
It also explains why two neighbors can get very different results. One tested a finished basement, the other tested a first-floor bedroom. For a decision about mitigation, the test that counts is the one from the lowest level anyone spends time in.
Radon results by decade in ZIP 17360
| Decade tested | Tests | Median pCi/L | 4+ pCi/L |
|---|---|---|---|
| 2000s | 333 | 10 | 68.5% |
| 2010s | 876 | 7.6 | 63% |
| 2020s | 285 | 4.6 | 55.4% |
The share peaked in the 2000s at 68.5% and sits at 55.4% for tests since 2020. A drop that size is mostly about who is testing, not the ground. More recent tests come from home sales and from retests after a system went in, and both pull the share down. The rock under Springfield Township has not changed. 285 tests have been logged in 17360 since 2020, so people here are still testing.
Housing in Springfield Township and what it means for a system
Census Bureau, American Community Survey 2020 to 2024:
| Springfield Township | York County | |
|---|---|---|
| Homes (housing units) | 2,341 | 189,857 |
| Median year built | 1987 | 1976 |
| Built before 1940 | 6.3% | 18.3% |
| Built before 1980 | 38.2% | 54.8% |
| Built 2000 or later | 36.8% | 20.6% |
| Single-family detached | 81.8% | 64.3% |
| Attached (rowhome, townhouse) | 14.2% | 17.1% |
| Mobile homes | 2.1% | 4.1% |
| Owner-occupied | 90.7% | 76.3% |
36.8% of the homes here were built in 2000 or later, one of the higher shares in the county. New construction is not radon-proof. A tight modern house can hold radon in as well as it holds heat in. Some builders rough in a passive vent pipe during construction, which makes a later active system cheaper, so check for a capped pipe in the basement. More on that in radon in new construction.
81.8% of homes in Springfield Township are single-family detached. A detached house with a basement is the easiest layout to mitigate: one suction point through the slab, a fan outside or in the garage, and a vent above the roof line. It is the standard sub-slab depressurization job covered step by step on our mitigation process page, and it usually lands in the middle of the cost range.
Cost-wise, a newer house with a passive pipe already roughed in can come in under the usual $800 to $1,500, since the installer mostly adds a fan and a gauge. Full ranges on the cost page.
